Here are 11 amazing prog rock supergroups you probably never knew about!

Supergroups have been a regular part of progressive rock since the dawn of the subgenre, with the first one – Emerson, Lake & Palmer – bringing together Keith Emerson (ex-The Nice), Greg Lake (ex-King Crimson) and Carl Palmer (ex-Atomic Rooster) in 1970.

Since then, several other big supergroups have emerged, including Asia, Transatlantic, and U.K. (in addition to progressive metal projects such as Sons of Apollo and Liquid Tension Experiment). Yet, there are exponentially more remarkable ones that too few people know about, which is why we’re writing – and you’re reading – this list!

We’re not saying that all of these collectives were (or have been) active for a while and/or produced a lot of work, nor are we suggesting that every member of every act was a huge star beforehand.

Keep in mind, too, that we’ve put this list together for prog lovers and prog novices alike, so while genre experts might know about some of these acts, broader rock audiences almost certainly won’t. Of course, there are also groups that often elude even the most passionate prog rock historians.

Now, get ready to discover some great new collaborations as we uncover 11 amazing prog rock supergroups you probably never knew about!
